#交易对 cryptocurrency trading pairs are the core mechanism of the cryptocurrency market, and their liquidity, depth, and transaction fees directly affect trading efficiency. Mainstream trading pairs (such as BTC/USDT, ETH/BTC) have high liquidity and are suitable for large transactions; niche altcoin trading pairs are highly volatile, presenting both risks and opportunities. Platform token trading pairs (such as BNB/BTC) often enjoy fee discounts, but one must be cautious of the platform's inherent risks. The rise of cross-chain trading pairs (such as WBTC/ETH) has addressed the issue of asset interoperability, but relies on the security of bridges. It is recommended that traders prioritize mainstream trading pairs to avoid slippage losses caused by insufficient depth, while also keeping an eye on updates to trading pairs to timely capture new asset opportunities. A rational view of the short-term volatility of trading pairs is necessary, as long-term value is key.
